FIREPROOF PLASTER lNG- SUPPORT.

SPECIFICATION forming part of Letters Patent No. 606,387, dated June 28, 1898.

Application filed January 6,1897- Serial No. 618,178. (No model.)

To all whom it may concern:-

Be it known that I, ALBIN KiiHN, architect,

a subject of the Grand Duke of Saxe-Alten bliirg, and a resident of Heidelberg, in the Grand Duchy of Baden, Germany, have invented certain new and usefulImprovements in Fireproof Plastering-Supports, of which the followingis a full and clear specification.

The improvement herein described consists of a wire-netting D, having stiffenings V or V connected therewith in a parallel arrangement, which permit the same to be easily stretched and securely fastened in such a manting and destined to receive the soft mortar can, after the mortar has hardened,be entirely burned to ashes without the plaster-work being destroyed.

Moreover, this combined fireproof plastering-support acts as a damper of sound and an isolator of heat and cold to the same degree as these qualities are possessed by the mortar-holding bed used therefor; but the main advantage of the latter is that its capacity for holding the mortar allows the use of wirenetting with very wide meshes.

Figure 1 shows this plastering-support in a form of execution wherein the wire-netting D with wide meshes is secured over the reed lining in such a manner that the stiifenin gs V run crosswise to the reed-stalks, whereby the reed lining is evenly pressed on and receives a second strengthening, which, moreover, prevents rents and bumps from occurring in the plastering-surface. However, it may also be arranged that way that the stiffenings V or V run crosswise to the slats L. These stiffenings, made of strong wire or wire-heald or the like, can. be either straight, as shown at V of Figs. 1 and 2, or in zigzag form, as shown at -V of Figs. 1, 1 and 3. The straight stiffenings V, as in Fig. 2, inclosed by the meshcrossings,have this particular advantage,that they can always be inserted afterward at any chosen place. The zigzag-shaped stiffenings V, which may best be arranged as strengthened meshes of thenetting D, as shown in Fig. 3, have this particular advantage, that when the nettingis stretched a lateral con traction is avoided and that the zigzag shape, embedded in mortar, offers an efficient resist ance against pressure. 1

If a wire-netting especially like Figs. 2 or 3 is chosen the stiffenings may eventually be left out altogether, since itsrows of meshes, being like spirals hung loose into each other, can be of themselves easily stretched and secured and because these rows of meshes, as shown by. the sectional plan, Fig. 2, form small arches entering into the plastering mass and which, enveloped in mortar, already give great stability to the whole construction. Since the reedwork covered in this manner with wire-ncttin g D has considerable stability,

this combined plastering-support can be advantageously used both on slabs and onslats. In the latter case, however-for instance, as shown in Fig. 1-the slats L, the stiffenin gs V or V, and the wires B securing the reeds must be kept at equal distances.

This wire-netting, strengthened in parallel direction, as shown in Figs. 2 or 3, of any chosen shape of meshes, can also be used by itself as a plastering-support, provided a narrow mesh be chosen in that case.

The wire-web D, being stiffened by the wires V, is heldto the base R of reeds or the like by nails or staples V, which engage the stiffening-wires and extend through the base and into the laths L, as indicated in Fig. 2.

1. In combination, with the slats, the foundation R of reeds, rushes or the like, the wire- Web applied over the foundation, the stiffening-wires passing through the wire-web and the nails or staples engaging the stiffening wires and passing through the foundation into the laths.

2. In combination,the foundatiomthe slats, the wire-webbing applied over the foundation and the stiffening-wires running through. the web, substantially as described.
